Connecting the DES-3224 to the
Network
This chapter covers the following:
• Cable Specifications
• Ports
• Connecting the DES-3224 to another DES-3224
• Connecting the DES-3224 to other switches and hubs
This section deals with making cables and connecting the DES-3224 to other devices. It is
extremely important that cables have the correct pin arrangement and that the proper cables
be used when connecting to servers, switches, hubs, workstations and other devices.
Cable Specifications
3
The type of cable you use depends on the speed of your network. A network running at 10
Mbps can use lower grade cable than a network running at 100 Mbps., Table 1: Cable
Length, indicates cable requirements for Ethernet and Fast Ethernet.
Table 1: Cable Length
Ethernet Type Cable Requirements Maximum Length
10BASE-T Category 3,4, or 5 UTP or STP 328 ft (100 M)
100BASE-TX Category 5 UTP or STP 328 ft (100 M)
Do not use telephone cable. Telephone cable does not support Ethernet or Fast Ethernet.
Use the following guidelines when handling cables:
• Do not stretch or bend cables.
• Do not put cables near sources of electromagnetic interference.
• Do not create trip hazards by laying cables in aisles and walkways.
• Secure cables to the floor when routing in aisles or walkways.
In order for Ethernet or Fast Ethernet to work the wires must be arranged correctly inside the
RJ-45 connector when you make cables. The most common problem on Ethernet or Fast
Ethernet networks is the cable. If you migrate from Ethernet to Fast Ethernet, make sure the
cables are pinned out properly.
There are two types of cables: straight through and crossover. Category 3, 4, or 5 UTP/STP
cable has eight wires inside the sheath. The wires form four pairs. Straight through cable has
the same pin out, inside the RJ-45 connector, at both ends. Crossover cable has a different
pin arrangement at each end. Fast Ethernet does not tolerate incorrect pin arrangements. You
Connecting the DES-3224 to the Network

10/100 Auto Negotiation Switch User’s Guide
must use the correct pin arrangement in order for the DES-3224 to work properly. See Figure
4 for an example of straight through and crossover cable. Table 2: Cable Requirements
shows the cable specifications.

10/100 Auto Negotiation Switch User’s Guide
Ports
There are three types of ports on the DES-3224: MDI-II Uplink, MDI-X and RS-232. The
difference between the MDI-II Uplink port and the MDI-X ports is the internal pin
arrangement.
MDI-II Port
An MDI-II port is a straight through port. The pin arrangement is the same as the pin
arrangement of a straight through cable.
MDI-X Port
MDI-X ports are crossover ports. The pin arrangement is the same as the arrangement in a
crossover cable. The advantage of an MDI-X port is that you can connect a device with an
MDI-II port without using a crossover cable. Just make a straight cable, plug it into the
MDI-II port and plug the other end into another device.
Table 3: Cable Connections, displays the proper cable to use when connecting to various
devices.
Table 3: Cable Connections
DES-3224 Workstation with MDI-II Port
MDI-II Crossover Straight Crossover
MDI-X Straight Crossover Straight
The steps for connecting the DES-3224 to 10 Mbps devices or 100 Mbps devices are the
same. All the ports will auto negotiate the proper speed and duplex mode. The DES-3224 has
two rows of 12 MDI-X ports.
Follow these steps to connect cables to the DES-3224:
1. Check for the appropriate cable configuration for each device.
2. Plug one end of the cable into the MDI-II Uplink port, if appropriate, or any of the
MDI-X ports.
3. Plug the other end into the appropriate port on the other device.
4. Verify that the LED indicates connection at the proper speed and duplex mode.
Other device
MDI-X MDI
RS-232 Port
The RS-232 Port is located at the rear of the DES-3224. The RS-232 port is a female port
that is used for serial communication. By connecting the DES-3224 and a PC you can
configure the DES-3224 and check its status and configurations even when the network is
down. Use the RS-232 cable provided to connect the DES-3224 and a PC.
Connecting the DES-3224 to the Network

10/100 Auto Negotiation Switch User’s Guide
DES-3224 to DES-3224 Connection
There are two ways to connect DES-3224s together: MDI-II uplink port or MDI-X ports. See
Table 3: Cable Connections for the proper connections to use with each type of port. The
DES-3224 is also compatible with the DES-5016 and DES-5024. Port Trunking can be
configured on the device if more than one port is connected between two DES-3224s or if
more than one ports is connected between a DES-3224, DES-5016 and DES-5024. Port
trunking increases the efficiency of the DES-3224 by increasing the bandwidth. See the
section on Port Trunking in Chapter 5 for instructions on how to configure Trunked ports.
Connecting the DES-3224 to the DES-5024 and
Hubs
You can connect the DES-3224 to other switches and hubs on the network. The DES-3224
and the DES-5024 are compatible products that can be connected easily. If you create
multiple connections between devices, create Trunked ports for more efficiency. See the
section on Port Trunking for more details. Determine the type of port you will be connecting
to and refer to Table 3: Cable Connections for the proper cable connections to use.
